A kidnapped woman manages to jury-rig a smashed telephone and dials a random cell phone number, reaching a young man who becomes her only lifeline as she desperately tries to communicate her location before her captors discover the call. The ingeniously simple premise generates real-time tension as the stranger must keep the fragile connection alive while navigating Los Angeles traffic, police skepticism, and the kidnappers' escalating violence. Kim Basinger brings genuine terror to her confined role while Chris Evans, in an early leading performance, carries the film's breathless momentum through its tight 94-minute runtime.
